-Devil May Cry 5
-Resident Evil 7 (or Resident Evil 2 remake footage, one or the other, though I doubt they'll give us both)
-God of War 4
-New KojiPro game
-New Sony IP
-New FFVII Remake footage.
-Parasite Eve 4 (highly doubtful, but crazier things have happened at E3)
Also, Capcom has at least one more unannounced PS4 project underway, I'd like to know what they have cooked up next. I'm hoping it's a new Onimusha or Dino Crisis, a DC reboot has been rumored for years now.
I'd also like to see The Last of Us 2, but that sounds like wistful thinking. I doubt they're very far in production, let alone have any footage to show, though they are reportedly working on that next after they wrapped up Uncharted 4.
Also wistful thinking: Sega announces a new HotD, Streets of Rage, or Sonic Adventure 3 for PS4. Also not gonna happen, they've been almost as neglectful of their IPs as Konami.
